# Other users can’t edit the network connections

If you can edit a network connection but other users on your computer can’t, you may have set the connection to be available to all users. This makes it so that everyone on the computer can connect using that connection.

Open the Activities overview and start typing Network.

Click on Network to open the panel.

Select Wi-Fi from the list on the left.

Click the settings button to open the connection details.

Select Identity from the pane on the left.

At the bottom of the Identity panel, check the Make available to other users option to allow other users to use the network connection.

Press Apply to save the changes.
